ELECTRIC-LAMP FIXTURE.

Application filed May 27, 1914.

To all whom it may concern f Be it known that I, THYGE NELSEN, zen of the United States, residing at cago, Illinois, have invented certain new and useful Improvements in Electric-Lamp Fixthe following is a specificaa citi- Chi- My invention relates to improvements in electric lamp fixtures and has especial reference to side brackets and ceiling fixtures doors exposure and which are weather resistant and water proof.

Some of the general objects of my invention are to provide ra lamp bracket, for porch lights, such as are usually secured to side walls of a door of the main entrance of a building, or used in other like 'exposed situations, so designed and arranged that it may readily be made heavy, of cast iron, quickly .and inexpensively assembled, without rel quiring and adapted a great deal of tooling,

after it has to permit of convenient wiring, been installed.

Another object is to so arrange the parts that moisture, due cannot remain in the hollow portions thereof, thereby to destroy the structure by freezing and by breaking down the insulation of the electric conducting portions.

' y Other and more specific objects of my invention will become readily apparent to persons skilled in the art froml a considera-- tion of the following description when taken Ain conjunction with thedrawin gs, wherein- Figure 1 is an elevation of the fixture showing parts in section. Fig. 2' is' a transverse section, taken on line 2-2 of Fig. 1. Fig. 3 is an enlarged sectional view, showing the manner of securing the lamp socket to the globe holding support. Fig. 4: is a modification showing another method' of securing the socket, of a different type, to the support.

In all the views the same reference characters are employed to indicate similar dated February 24th, 1914,

may be a pipe or the like, for securing thev fixture thereto.

7 is a hollow stem, screw threaded to the support 6, for maintaining the fixture in its position.

8 is a canopy surrounding the stem and se- Surgd in place thereon by thel friction screws The stem 7 terminates in an enlarged end or head l0 which is transversely perforated, on each of its sides, by an angular opening 11. The opening is shown generally round for the y most part being tangentially cut away at opposite diameters to prevent a similar formed object, that may be inserted within the opening, from being turned around or rotated therein. The stem 7. is also provided on one of its sides within the canopy 8, with an opening 12', having preferably rounded edges to prevent chafing of the electric wires.

A cup shaped socket-receiving member, 13 is provided with an outwardly flanged edge 14, near its top, and with a cylindrical projection or hollow boss 15 extending from its bottom. The cross section ofthe cylindrical projection l5 is substantially the same as the openings 11 provided in the head 10 of the extension 15 is placed within either of the openings 11-11, the cup portion 13 cannot be rotated, with reference to the head 10, a'nd as both ends of the enlargement are provided with openingsY 11, the cup member 13 may be placed in either' lot the openings `so that the lamp which is supported on the cup hang downwardly or may be supported, as shown in the drawings.

Projecting from the cylindrical portion 15 is a nipple 16, which may be an integral portion of the part 15 or it may be a separate portion, such as a threaded pipe nipple, secured thereto as by screw threads, or the like. The nipple 1G projects toward the opening in the lower portion of the head 10, for screw threaded engagement with the nut 17. The' nut 17 is provided with a shoulder 18 and a cylindrical guide portion lf) which enters the open-ing 11 on the opposite side of the enlarged head 10. and since the guide portion 19 is not angular but round in cross section, the nut may be turned within the V opening 11 to secure the parts to the head.

ed by walls with tapered and rounded surface so as to prevent chafing of the wires and to permit easy threading of the wires through the cup 13 and into the hollow stem 7 and through the opening 12 made therein after the device has been installed. The nut 17 is hollow and is l providedwith a drain opening 2l at the bottom'of the hollow portion, to permit the water which may be received in the interior through the thimble 16 or through the interior of. the cup shaped portion 13 to drip out. A similar opening 22 for the same purpose, is provided in the lower portion of the head 10, and another opening 23 of generally similar character for the same purpose, is provided in the globe holder 24. The globe holder 24 is counter sunk, to provide a recess for the reception of the flange 14, of the cup member 13, the parts being held .together by means of screws 25 of which a suitable number may be employed. The globe receiving portion of the holder 24 may be of varying diameter, to accommodate lthe different styles, 'sizes and types vof globes, 26. One of the impor.- tant features of my invention is the perforate raised socket-holding portion 27, of the holder 24. The raised portion 27 is pro-- vided with an inwardly projecting flangeeL 28 to provide a rim against which to secure the socket 29.

The socket 29 of a well known type consists of the major portion 29a and the minor portion 29", the latter being screw threaded inthe shell 30, to hold the parts together, and between the parts the flange 28 of the globe holder is included. The socket 29 of another type, may be secured to the flange 28, by means of a thin ring 31 which no`rymally is concavo-conveX and in the position shown in dotted lines at 32 and Which, after the parts have been 'placed in position on the globe holder 24, is flattened out soas to decrease its internal diameter and thereby produce a gripping effect upon the body part of the socket 29 to hold the socket securely in place, with'reference to the globe holder.

In assembling the device, after the parts including the cup 13 have been placed in position upon the. side wallsp, the screws 25 are taken from the globe holder and the socket 29 or 29', as the case may be, is se- 'curely fixed in the elevated portion 27 ofthe globe holder, in the. manner heretofore described. The wires 33 are then attached to the socket, slightly curved and threaded through the relatively large opening 20, and along the hollow stem 7, and out through the opening 12. The parts are so relatively large and the openings are so amply suflicient for the purpose that there is no difficulty in threading the ywires 33 through the said parts and out through the opening 12, readily accessible when the canopy 8 is loose upon the stem 7, and pushed toward the enlarged head 10, to permit an opening between the edge of the canopy and thel vertical wall After this has been done, the globe holder, 24 is-plaeed back in position over the flange of the cup so that the counter sunk portion thereof registers with the flange 14 of the cup 13, and the screws are placed in position to hold the cup 13 and the'. globe holder 24 together. The vglobe 26 may then be placed on the holder' and secured thereto by the screws 26.

The lamp is adapted to be screwed into the threaded shell 30, of the socket 29, before the globe 26 is placed in position on the globe holder 24.

i While I have herein shown a single embodiinent of my invention, for the purpose of clear disclosure, it is evident that changes may be made therein, within the spirit and intendment ofthe claims, without departing from the scope thereof.

Having 'described my invention, what l claim 15:.- ,a A. 1.
